IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No 61,633, dated April 6,1875 5 application filed August 15, 1874.

To all whom it may concern Beit known that I, CHARLES W. PATTON, ofLouisville, in the county of Jefferson and State of Kentucky, haveinvented a new and valuable Improvement in Ghurns; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings making a part of this specilication, and to the lettersand figures of reference marked thereon.

Figure 1 of the drawing is a representation of a sectional view of mychurn. Fig. 2 is a detail view ofthe same.

This invention has relation to churns ofthe upright kind, wherein arotating' dasher is employed; and it consists in a circular concavedisk, which is applied on the dash-rod in an opening made in the coverof the churn-box, and which prevents milk from dashing out of the boxwhile churning, and serves, in combination with the cap-bearin g, toexclude foreign matters from the box.

In the annexed drawings, A designates the press-box, which is shapedlike a conic frustum, and provided with a cover composed of two parts, ca. B designates the dash-rod, which has a slot, b, diametrically throughit to receive the dash-blade C, Which slot is somewhat longer than thelength of the blade to allow the latter to be inserted and removedreadily. The blade C has a notch, e, in its lower edge adapted toreceive a portion of the rod B at the lower end of the slot b, thusholding the blade firmly at its lower end. By thus notching the blade onthe rod B a single pin, c, will complete the fastening and allow theblade to be removed for cleaning the parts. The lower end of thedash-rod B is stepped in a bearing on the bottom of the box A, and onthe upper end of this rod a thimble, d, is secured, having fixed to it aspur-wheel, f, a concave disk, 7c, and a central pin, h. The pin h hasits bearing in the center of a hollow cap, D, which covers the openingz' through the cover section a, and which is rigidly secured upon ,thissection by means of screws applied through the arms jj. Below thespur-wheel f is the concave disk k, which is circular, concave on top,and of larger diameter than the hole t', through which wheel f ispassed. rIhis concave disk k will prevent anything from falling throughholes t" into the milk while churning, and it also prevents the milkfrom being dashed out through the holes i. Gr designates a drivingspur-wheel having a crank-handle, G', secured to it, which wheel isapplied on a stud, l, fixed to an adjustable plate, E, on thecover-section a. Wheel Gr engages with the wheel f, and for this purposean opening must be made through the cap to, allow wheel G to enter it.The cap D thus holds wheel Gr down on its stud. Inside of the churn-box,and removably secured to its side wall, are a number of abutments, a,which, in cross-section, are T-shaped, and adapted to slide between lugsu. The back flange of each abutment is inclined to correspond to theinclination of the wall of box A, but the front flange is vertical orparallel to the edges of the dash-blade. These blades or abutments narrest the currents induced by the dash-blade, and materially aid inbringing the butter.

It will be observed that the cover to the box A is made of two parts,the largest part bearing the mechanism for operating the dash-rod, andthe smaller part, a', allowing inspection ot' the contents ofthe churnwithout removing the larger part. These two cover-sections are held inplace on top of the box A by means of lugs formed on this box andgrooves made in the edges of the sections.

Itis obvious from the above description that my improved churn can beused to advantage in the manufacture of ice-cream.

It will be seen that the disk k, situated in the recess@n of the cap a,is made concavo-convex, so that its outer edges will-project up andnearly in contact with the upper face of the recess t'. Thisconstruction is very important, as it will prevent any oil from thegearing or dirt falling into the cream, the former beingheld in theconcave part of the disk, and, if thrown to the outer edge of said diskby its centrifugal action in the rotation of the churndasher, wouldimpinge against the lower face of the recess i and be thrown back intothe concave part of the disk. By placing the disk 7c in the recessedpart ofthe cap a another result is attained, the convex form of thelower face of the disk guiding any milk splashed upward by the dasher tothe outer periphery of the recess i, Where the outer edge of the disk Itis nearly in contact with it, thereby leaving no space for the escape ofmilk or ingress of oil or dirt.

I am aware that a churn has heretofore been constructed provided with aninverted vessel having an opening at its top t0 prevent the escape ofmilk in the rotation of the dasher; and I therefore lay no claim to suchinvention, as by my construction I dispense entirely With such invertedvessel, and employ a concaveconvex disk attached to the dasher-shatt andrecessed in the cap, which performs the double function of preventingthe ingress of dirt and Oil into the churn, or the egress of milktherefrom, whereas the inverted conical vessel disclaimed will serve toguide the milk thrown upward by the dasher through its opened end.
